I Am A 65 Year Old Female. Over A Year

I am a 65 year old female. Over a year ago I had a suspected bout with diverticulitis. By the time I got into a gastro doctor weeks later a MRI with contrast was done and the Doc said he could see some residual spasms. He recommended Fiber Con, one a day to avoid constipation. I had pain with this episode. Last Thursday early AM I woke with chills and nausea. No pain at all. Diarrhea and some vomiting. For two days I had water, tea, some soda crackers, no caffeine, felt better and started with soup and broth, then added turkey and white bread. I used pepto for two days and was doing much better. Went off that on Sunday and that stopped the loose stools. No BM for a day plus. Monday after the pepto BM Orange diarrhea began, very acidic. I am feeling pretty well but the acidic BM continues, five today thus far.
